LEVER.

Application filed. May 28, 1924. Serial No. 716,515. I

To aZZ w from it may, concern Be it known that we, DONALD nsLnr PnoK andROBERT DANFORD MoALLrs'rnn,

both subjects of the King of Great Britailn and both residents of thecity of Vancouver, in the Province of British C0lumbia,Oanada, haveinvented certain new and useful Improvements in Levers,of which thefollowing is a specification.

, Our invention relates to improvements in levers which are particularlyadaptable for use on automobile brakes and the like, the objects of theinvention being to provide means whereby lever latching means isactuated by a handle which'forms the operating handle of the lever, afurther object is to provide a simple means whereby the latching meansof the lever may be conveniently locked to prevent any unauthorizedmovement of the lever.

The invention consists essentially of a lever having an operating handlehingingly mounted thereon and a lever latching rod connected to thehandle to be actuated thereby, as will be more fully described in thefollowing specification in which Fig. 1 is a sectional view showing thelever locked against operation.

Fig. 2 is a fragmentary view showing the lever handle in position fordisengaging the latching mechanism. 7

Fig. 3 is a sectional view taken on the line 33 of Figure 1.

In the drawings like characters of reference indicate correspondingparts in each figure The numeral l'indicates a lever which is preferablyof hollow'construction. The lever is fulcrumed upon a shaft 2 and isprovided with a downward extension 3 to which the brake rod 4 isconnected. The base of the lever is slotted to accommodate a brakequadrant 6 which is provided with ratchet teeth 7 Hingingly mounted atthe upper end and to the forward side of the lever 1 is a handle 8 whichis provided with an exten sion lug 9 having a stop 10 which is adaptedto contact with the front wall 11 of the lever when the handle is innormal position and to contactwith the rear wall 12 when the hand isthrown forward to raise the latching means from the quadrant 6.

The numeral 13 indicates a latch rod, pin connected as at 1% in aslotted aperture 15 in the heel of the handle 8 and having at its lowerend a dog 16 which is adapted to engage the teeth? of the quadrant 6 tohold the lever in any desired position. The rod isslidably mounted in ablock 17 adjacent the quadrant and a further block 18 adjacent thehandle and is provided with a fixed collar '19 between which and theblock 18 a spring 20 is mounted for the purpose of de pressing the rod13and for holding the handle 8 in alignment wtih the lever 1. A block 21is secured to the rod 13 which is provided with a transverse groove 22the purpose of which will appear later.

A look 23, preferably of the cylinder type is mounted exterior-1y of thelever 1 and is provided with a rotatable latch tongue 21 which isadapted to swing into engagement with the groove 22 of the block 21 whenthe key 25 is in position for removalfrom the lock, and to swing clearof the block 21 when the key is turned to one side.

Having thus described the several parts of our invention we will nowbriefly explain its operation.

To apply the brake 1t sufiices to draw the lever 1 rearwards when thedog 16 rides along the teeth"? of the quadrantG and the pin connection14 of the rod 13 slides within the slotted aperture 15 of the handle 8,when thehandle is released the dog 16 comes to rest against one of theteeth 7 holding the brake in set position.

An alternate method is to tilt the handle forward causing the pinconnection to engage the lower end of the slotted aperture 15 andraising the dog clear of the teeth of the quadrant until the desiredposition of the lever is obtained, when restoring the handle to normalposition latches the brake dog 16 to the quadrant.

To release the brake it suffices to hold the lever against movementandto tilt the han dle forwards when the dog is raised from contact withthe quadrant teeth and the le What we claim as our invention is:

1v A device of the character described comprising a hollow lever pivotedat its lower end, a rack bar passing transversely through the leverabove the pivot, a latch slidable in the lever for engaging'the teeth ofthe rack bar to hold the lever in a set position, a rod extendingupwardly from the latch, a handle pivoted to the upper end of the leverand provided with a segment shaped portion adapted to be receivedwherein the lever when the handle and lever are in aligned position,said segment shaped portion heing'vformed with a curved slot in which isengaged a pin carried at the upper end of said r0d,a springencirclingsaid rod, an abutment carried by the rod for engag- -ing oneend of the spring and a second abutinent carried by the-lever forengaging the opposite end of the vspring,and means for locking said rodagainst movement when the latch is engaged with theteeth of the rackbar.

2.'A structure according to claim 1, in which the segment shaped portionof the handle is formed to contact with opposite portions of the-leverto limit swinging movement of the handlein either direction.
